from my experience on playing on Manduolan, the guild Cow Eaters is not that active. Which made me search for another server. I found 库尔提拉斯 - Kul'Tiras (CN2) and the guild called Laowai Club.
Pretty active foreign players, 4 of them log in daily, with a total of around 6-7 logging in every week. In the guild are also Chinese players who have been very friendly and with whom you are able to run instance together.
It is a PVP server though, heavy in favors of the Alliance. I also leveled a few chars here, doing one now as well and I have had only a few encounters with gankers. - Be assured though, should you be ganked, I log in a few hours each day, just give me a shout in guildchat and IŽll remove them. =)
Think about it.
